SNMP

SNMP

The Services–>SNMP page allows you to enable the jetNEXUS ALB-X for SNMP agent.
The page is organised into the section below.

SNMP Settings

Simple Network Management Protocol (SNMP) exposes management date in the form of variables on the jetNEXUS ALB-X. These variables can then be queried by third party SNMP managing applications.

SNMP v1:
RFC-1157
SNMP V2c:
RFC-1901-1908
SNMP v3:
RFC-3411-3418. The username for v3 is admin. Example:- snmpwalk -v3 -u admin -A jetnexus -l authNoPriv 192.168.1.11 1.3.6.1.4.1.38370
Community String:
This is the read-only string set on the agent and used by the manager to retrieve the SNMP information. The default community string is jetnexus
PassPhrase:
This is the password needed when SNMP v3 is enabled and must be at least 8 characters or more and contain letters Aa-Zz and numbers 0-9 only. The default passphrase is jetnexus

SNMP MIB

The information viewable over SNMP is defined by the Management Information Base (MIB). MIB’s describe the structure of the management data and use hierarchical object identifiers (OID). Each OID can be read via an SNMP management application.

Historical Graphing

The best use of the edgeNEXUS Custom SNMP MIB is the ability to offload the historical graphing to a management console.

Below are some examples from Zabbix that polls a jetNEXUS ALB-X for various OID values listed above.
